Project Abstract
In the past year, we developed new, substantially enhanced versions of the SCEC Community Fault (CFM) and Statewide Community Fault (SCFM) Models in collaboration with Craig Nicholson (UCSB). The models were improved by updating fault representations using more precise fault traces and relocated seismicity, with an emphasis on refining fault geometry and segmentation along the San Andreas and San Jacinto fault systems. We also developed more than 70 new fault representations in northern California. These new models are currently being evaluated by the SCEC community and will serve as a basis for the Uniform California Earthquake Rupture Forecast (UCERF 3) working group efforts. Finally, we developed a new nomenclature system for the CFM that is more informative and consistent with the USGS Qfault database, enabling users to access and combine fault information more readily.
Intellectual Merit This research represents the development of an improved community fault model, which serves as the basis for a variety of SCEC science and hazard assessment objectives, including PSHA and strong ground motion prediction.
Broader Impacts This project has involved graduate students and research staff, and the results of improved hazard assessments provide the basis for reducing loss of life and property in future earthquakes.
